2025 SEAL Performance iTAC: a control function is not a differential-lock part number
Only Australian MY25 SEAL Performance lists iTAC. Separate the control function from unverified differential locks, actuators and supply boundaries.
Seeing iTAC in a repair or modification enquiry can prompt a request for a “torque distributor” or differential lock. Establishing this control function's identity on Australian MY25 SEAL Performance helps avoid turning a function name into an unverified hardware order.
The factory lists it only for Performance
The corresponding table lists the iTAC torque-control entry as fitted only to Performance, with Dynamic and Premium not equipped with that item.[Factory equipment][Q07] An explicit model-year designation in the local brand network supports MY25 Performance identity; it is not inferred from a filename or registration year.[Model-year reference][Q29]
This confirms equipment allocation. It does not identify a separate mechanical differential lock or individually orderable actuator from a single control-function entry.
Driving behaviour and component identification require different information
For driving or system-message complaints, record actual behaviour, messages, software status and repair findings rather than attributing every traction or power change to iTAC in advance.
The product table provides no intervention thresholds, specific controlled components or replacement criteria. A single driving impression cannot establish normal operation or a fault, and this article provides no road reproduction test procedure. [To be verified]
Do not borrow another brand's limited-slip technology to fill in the construction
The e-LSD on MG7, the rear differential lock on T60 and this vehicle's iTAC have different names and evidence boundaries. Procurement should follow this vehicle's diagnosis and catalogue identity. Do not combine these technologies into one interchangeable hardware explanation or infer retrofit plans for other trims from Performance equipment.
Scope and verification
This article covers only Australian MY25 BYD SEAL, Performance; excluding Dynamic/Premium. The cited function and equipment information is not a fault or replacement criterion.[Scope reference][Q29]
No public data was available in the reviewed material for iTAC control strategy, associated hardware, thresholds and behaviour in different conditions; diagnosis and calibration, repair parameters, replacement criteria, OE numbers, separate parts availability or interchangeability. [To be verified] Verify compatibility or interchangeability using the VIN and local Australian manufacturer parts catalogue.
